I have used these clutch springs in my yz250's and they have worked out great. they obviously add a little more tension when pulling in the clutch lever but I just make sure my cable is well lubed with WD40 and my clutch lever perch pivot is cleaned and greased. I think the added clutch pull is worth saving the clutch. The springs are about 3 mm longer than the new stock springs so that's probably how they added the tension to the springs. They seem a little expensive but I just bit the bullet figuring its better than replacing the entire clutch. They do seem to make the clutch last longer.

I've been riding kawasakis for years and always had a hard time getting my clutch plates to last. Finally I put a good OEM clutch with pro circuit springs and no more issues! now this is the first thing I order when I get a new bike.
As always, Pro Circuit's products are top notch, these springs aren't any different.. Works much more efficiently than the stock springs and grabs a lot harder. The pull isn't much more than stock, but it takes a little more effort. Install is straight forward and quick. I would definitely recommend these clutch springs to anyone looking to buy some!
Best springs on the market
Great stuff.. necesary for pepole use a lot of time the clutch
I installed these clutch springs in my 09 CRF450R to reduce clutch slip. They do work and totally eliminated the slipping, but are really stiff at the lever pull. After a few laps you can really notice it and increases forearm pump.
I would recommend these to anyone that has a bike. Even If your running a stock clutch these springs will make a diffrence. I have these in my 250f and 450f. I don't notice the stiff pull at all. what I do notice is the more reaction in the clutch when in hair pin corners and starts.
I put these springs in with a Barnett Dirt Digger clutch on my 2007 CRF450. Springs make it hard to pull lever, but in time they rip. Only springs I will use in the future. Price worth the performance!!
Well worth the price.They provide the extra grab when you need it. Even though they are stiffer,its not hard to get use to.
These springs are really nice, installed them on my 06' kx250f along with some new Hinson friction plates. The difference is like night and day. I heard people complaining about a stiffer clutch pull but I haven't noticed even in long moto's. Maybe if you had wuss hands or something. The clutch grabs hard and doesn't pop out on me any more. They make your plates last longer too by reducing slippage. Super easy to install as well.
These are great clutch springs. I put them on a 2004 rmz 250 and i can definantly feel the difference. The install was very basic and simple. If you ride single track trails/ pull in your clutch a lot then you will notice that they are 30% stiffer when you pull you lever. Great for track use and getting the holeshot starts because they make your motor grab harder.
